Fig. 12 is across-section taken on line 12-12 of Fig. 10;

Fig.'13 is a cross-section taken on line I3 -l3 of Fig. 10.

Referring now more particularly to Fig. 1 of the drawings, the entireapparatus is mounted on a base plate l0. Beneath the base plate Hi,there is suspended a bracket H which support a rotatable drive shaft 12.The shaft 12 may be driven in any suitable manner known in the art. Forexample, it may be driven in the same manher that shaft BI is shown tobe driven in United States Patent No. 2,012,185. A tripping mechanism,such as that shown in United States Patent No. 2,018,881, may beincorporated to initiate the rotation of the shaft 12 after the playingof one side of a record by the phonograph.

A cam means I3, preferably in the form of a cam wheel, is mounted on theshaft 12 to rotate therewith. On the periphery of the cam wheel I3(Figs. 1 and 3), there are provided the cam elements 14 and |5--I5.Between the cam elements l5-l5, there is provided an adjustable memberI6 which is biased in the position shown in Fig. 3 by a spring H. Theadjustable member 16 is adapted to be moved in a clockwise direction(Fig. 3) in response to a force suflicient to'overcome the biasing forceof the spring H.

The cam wheel I3 is also provided with a sub common area between the camgrooves 2| and 22. The switching element 23 is provided with a pin orextension 24 which is adapted to move in a slot 25 formed in the camwheel IS. The pin 24 is adapted to move in the slot 25 as the switchingelement 23 is pivoted from the full-line position to the dotted-lineposition shown in Fig. 1. The switching element 23 has formed thereon atoe 26 and heel portions 27 and 26. The purpose of the switching element23 is to open and close the entrance to the cam grooves 2| and 22, in amanner to be described hereafter.

A pin 29 on a movable member 36 is adapted to cooperate with th camgrooves |8--22, while the cam wheel I3 is rotating. If the switchingelement 23 is in the dotted-line position shown in Fig. 1, while the camwheel I3 is rotating through a cycle of operation, the pin 29 will movein the cam grooves l6, i9, 22 and 26, which is the second cam pathreferred to above. If the switching element 23 is in the full-lineposition shown in Fig. 1, while the cam wheel I3 is rotating through acycle of operation, the pin 29 will follow the cam grooves l8, l9, 2|and 26, which cam grooves describe the first cam path referred to above.While the pin 29 is in. the groove 22, it engages the heel 28 to movethe switching element 23 from the dotted-line to the full-line positionshown in Fig. 1. 'While the pin 28 is in the groove 2|, it engages theheel 21 to move the switching element 23 from the full-line tothedotted-line position shown in Fig. 1. The movable member 36 and the camwheel B3 are adaptable to cooperate with the record-reversing mechanismand the record-changing mechanism described in United States Patent No.2,012,185 to carry out record-reversing and record-changing cycles,respectively.

A lever or connecting member 80 is pivotally supported in a suitablemanner preferably on an arm 32 provided on the bracket M (Figs. 1 and3). On one end of the lever 3|, there is provided a pin 33 which ismaintained in the path of the cam elements ||5 and the adjustable memberit, while the lever 3| is maintained in its normal position shown bydotted lines in Fig. 3. A member 34 is pivotally mounted on the oppositeend of the lever 3| and is biased by a spring 35 into engagement with anear 36 provided on the lever 3|, as shown in Fig. 3. The member 36 isadapted to be moved in a clockwise direction from the position shown inFig. 3 against the biasing action of the spring 35. The free end of themember 34 has a toothed portion 3?. the lever 3| and the other end ofwhich is fixed to a suitable body, normally maintains the lever 3|against a pin 39 provided on a suitable fixed object, such as a bracket46 (Fig. 3).

The lever 3| is adapted to cooperate with control mechanism forcontrolling the playing of a plurality of records on one side or on bothsides,

One embodiment (Figs. 1-4) includes a member or shaft 4| movably mountedon a bracket 42, preferably in the manner shown in Fig. 4. The member 4|extends upwardly from the bracket 42 and through an opening in the baseplate l6, as shown in Figs. 1 and 4.

At the lower end of the member 4|, there is provided a plate or a gear43 which is rotatable with the member 4|. The gear 43 has a plus ralityof perforations annularly spaced near its periphery, as shown in Fig. 3.The gear 43 is positioned to be engaged at its periphery by the pivotalmember 34 movable with the lever 3|.

A spring 38, one end of which is fixed to r When the lever 3| is rotatedin a'clockwise direction (Fig. 3), it transmits counterclockwisemovement (Fig. 3) to the gear 43. Below the gear 43, there is provided aratchet wheel 44 (Figs. 4 and 6) which also is rotatable with the member4|. A spring-biased pawl 45 is adapted to engage the ratchet wheel 44for preventing the clockwise movement of the member 4 I. Near theopposite end of the member 4|, there is aifixed thereto in a suitablemanner a plate 48 (Figs. 1, 2 and 4) which is perforated in the samemanner as the gear 43. The upper end of the member 6| is provided with amanual control bob 4! to enable an operator to rotate the member 4| andtherewith the plates 43 and 46 for settling the play-control mechanism.A plurality of control members 48, preferably in the form shown in Figs.1 and 4, are frictionallymounted in the perforations of the plates 43and 46and extend above the plate 46 and below the plate 43, as shown inFig. 1. The control members 66 are manually adjustable in a verticalplane relative to the plates 43 and 46 to two-different positions. Theuppermost position of the control members 48 will be referred to as afirst position, and the lowermost position 01. the control members willbe referred to as a second position. When the control members l8 are inthe second position and they move past a pin 49 fixed to the bracket 42,the control members 48 are moved back, automatically, to the firstposition. The control members 48 are also movable in unison with themembers 4|, 43 and 46 in a horizontal plane. The movement of the controlmembers 48 in a horizontal plane moves them successively past a pointer56, shown in Fig. 2.

An intercepting mechanism is associated with the control mechanism, justdescribed, the connecting member 3| and the switching element 23 tocooperate in carrying out the play-control operation. This interceptingmechanism is best shown in Figs. 1 and 2 and includes an electriccircuit. In the electric circuit, there are provided a movable contact5| and a fixed contact 52 which are mounted on the bracket 42 by theinsulatin means 53. The movable contact 5| is positioned in the path ofthe plurality of control members 48 which are in the second position andis moved into engagement with the contact 52 as these control members,in the second position, are successively moved into engagement with themovable contact 5|.

A lead 54 connects the movable contact 5| to a source of supply. A lead55 connects the fixed contact 52 to a solenoid 56 having a movablearmature 51. The solenoid 56 is supported on the bracket 46, preferablyin the manner shown in Fig. 7. The bracket 46 is fixed, in a suitablemanner, to the bottom of the base plate i6. A lead 58 connects thesolenoid 56 to a movable contact 59 which is associated with a contact66. Contacts 59. and 66 aresupported by insulating means 6| provided onthe bracket 46. The movable contact 59 is positioned in the path of thecam portion M on the cam wheel l3 and, when the cam portion I4 is movedpast the movable contact 59, it moves the contact 59 into engagementwith the contact 66. A lead 62 connects the contact 66 to the source ofsupp y.

One end of the armature 51 is associated with a U-shaped member 63having the legs 64 and 65. T e member 63 is pivotally mounted on thebracket 46, preferably in the manner shown in Fig. 7. The leg 64 of themember 63 normally rests on top of the armature 51 and is adapted to beraised from the full-line position to the dotted-line position shown inFig. 7 when the solenoid 55 is energized. When the leg is raised by theupper end of the armature 51, the leg 55 is moved out of the path of thelever 9|.

As has been previously described, the lever 3|,

which is normally maintained by the spring 99 in the dotted-lineposition shown in Fig. 3, is adapted to cooperate with the gear 43 andthe cam. elements |-|5 and I5. While the cam wheel I9 is rotatingthrough a cycle of operation, one of the cam elements l5 engages the pin39 on the lever 3| and begins to pivot the lever 9| in a clockwisedirection (Fig. 3) against the biasing action of the spring 38. Thecontinued movement of the cam wheel l9 brings the adjustable cam memberI 6 into engagement with the pin 99 (Fig. 3). If the leg 65 is in thepath of the lever 3|, the movement of 'lever 3| is stopped when itreaches a position midway between the dottedline and the full-linepositions shown in Fig. 3.

The stopping of the lever 9| by the leg 55 forces the adjustable memberIE to pivot in a clockwise direction (Fig. 3) against the biasing actionof the spring ii. If the leg 65 is out of the path of the lever 3 I, theadjustable member I6 is maintained in its normal position by the springl1 and moves the lever ill in a. clockwise direction to the fulllever 3|is in the full-line position shown in Fig. 3,

or in the midway position previously mentioned, the adjustable member l6and one ofthe cam elements |5 permits the spring 98 to move the lever 3|back to the dotted-line position (Fig. 3). The clockwise movement(Fig.9) of the lever 3| brings the toothed portion 31 of the member 94into engagement with the gear 43 and rotates it in a counterclockwisedirection (Fig. 3). If the lever 3| is moved the full distance from thedotted-line to the full-line positions shown in Fig. 3, the gear 43 andthe plate 45 are moved the distance between adjacent numbers on plate 49(see Fig. 2). If the lever 3| is moved only half the distance betweenthe dotted-line and full-line positions shown in Fig. 3, the gear 43 andthe plate 46 are moved only half the distance between adjacent numberson the plate 45. On the return movement of the lever 3| to its normaldotted-line position (Fig. 3), no movement is transmitted to the gear43. This is true because of the manner in which the member 34 isconnected to the lever 3| and because the ratchet mechanism includingthe members 39 and 45 prevents the rotation of the gear 43 in aclockwise direction (Fig. 3).

The lower end of the armature 51 (Fig. 1) is connected to one end of alever 66 which is pivotally mounted intermediate its ends to the bracket4|). When the solenoid 55 is energized and the armature 51 is movedupwardly during a cycle of operation of the cam wheel |3, the lever 5bis pivoted in a clockwise direction (Fig. 1). If the switching element23 is in the full-line position shown in Fig. l, the clockwise movementof the lever 66 positions its free end for moving the switching element23 into the dotted-line position (Fig. 1).

Another embodiment of the control mechanism, which is adapted to operatewith the lever 9| and the first intercepting mechanism de-' scribedabove, is shown in Figs. 9-13 and will be described now. r

This embodiment of the control mechanism includes a pair of bracketsl4--'|4 supported in a suitable manner beneath the base plate "I. Aplate II is connected to the brackets IL-l4, preferably in the mannershown in Fig. 10. The plate I! has a plurality of perforations annularlyspaced near its periphery, in which are frictionally mounted a pluralityof control members 19 to move from an uppermost to a lowermost positionrelative to the plate 15. When the control members Ii are in theiruppermost position, they will be referred to-as being in a firstposition, and when they are in their lowermost position, they will bereferred to as being in a second position. A plate 11 of insulatingmaterial is connected to the brackets 14-14 below the plate 15. Anannular member 19 (see Fig. 11) is provided on the top surface, of theplate 11. .This member is of electrical conductive material and has aneat 19 extending downwardly through an opening 8|) in the plate 11. Theear I9 is connected to. the line 55 of the electric circuit previouslydescribed. A

bracket 9| is connected in a suitable manner to the bottom of the plate|l.- A shaft 82 is connected to the bracket 9| to rotate relativethereto and extends upwardly through openings in the plates 11, 15 andIt, .as shown in Fig. 10. The upper end of the shaft 92 is provided witha control knob 99, by which an operator may rotate the shaft 82 in acounterclockwise direction (Fig. 9) to set the play-control mechanism.Intermediate the ends of the shaft 82, there is afiixed thereto in asuitable manner, as shown in Fig. 10, an insulating member 95 in theform of a sleeve. The member 95 preferably has a reduced portion 95 atthe lower end thereof and is provided withnotches 91-91 and 89 (see Fig.11). A member 99, having an annular portion 90, an extending portion 9|and a contact 92, is mounted on the reduced portion 95 of the member 85to rotate around the axis of the shaft 82. A pair of cars 9393,extending upwardly from the annular portion 99 of the member 99, isadapted to extend into the notches 9'|,-8'|. This mounting of the member99 permits it to rotate with the shaft 82. The contact 92 on the member89 is adapted to be moved into contact with the annular member I9 whenone of the control members 16 in the second position engages the-contact92. A member 94, having a turned-up end 95, is slipped over the reducedportion 85 in the manner shown in Fig. 10. An ear 91 on th member 94extends into the notch 99 of the member 85 and permits the member 94 tomove with the member 85 and the shaft 92. As the free end 95 of themember 94 (see Fig.- 12) moves past the control members 16 in the secondposition, it elevates them to their first position. In this manner,after the control members in the second position have served theirfunction, they are automatically moved to their first position. Anannular member 99 .is on the reduced portion 85 under the annularportion of the member 94. The annular member 98 is provided with an ear99 which extends through an opening in the plate 11 and is connected tothe line 54 of the electric circuit previously described. An annularinsulating member Hill is mounted on the shaft 92 below th reducedportion '86 of the.

to rotate therewith. A spring-biased pawl I03,

suitably connected to the bracket 8|, is adapted is adapted to rotatethe gear and the member 89 in a counterclockwise direction. Thismovement of the member 89 successively brings the contact 92 intoengagement with the control members in the second position for carryingout the play-control operation.

In order that the play-control mechanism functions properly, it isevident from the description of the invention that the switching element23 must be in the full-line position shown in Fig. 1 before thephonograph is initiated for operation. If the switching element 23 isnot in the full-line position (Fig. 1), it may be moved into suchposition by mechanism shown in Figs. 1 and 8. This mechanism includes aspringbiased rod I mounted on the bracket 40 in the manner shown inFig. 1. The upper end of the 4 rod I05 extends above the base plate I0and has a knob I06 provided thereon. The lower end of the rod 05 isadapted to be brought into engagement with an L-shaped member |01pivotally mounted on the bottom of the bracket 40. The legs of themember |01 are counterbalanced so that the member |01 normally is in.the full-line position shown in Fig. 1. The member I01 is movable in acounterclockwise direction from this position by pressing the rod I05downwardly against the force of its biasing spring. When the lever I01is pivoted in a counterclockwise direction from the full-line positionto the dotted-line position shown in Fig. 1, one end of the member I01moves upwardly. If the switching element 23 is in the dotted-lineposition shown in Fig. 1, then the member I01 engages the pin 24 andmoves the switching element to the full-line position shown in the samefigure. After the member I01 has moved the switching element 23 to thefull-line position (Fig. 1) and the lever I05 has been released to itsnormal position, the member I01, as a result of its counterbalance,moves back to its normal position, as shown in Fig. 1.

Mode of operation The mode of operation of applicant's invention willnow be described. Before setting into operation an automatic phonographin which applicants invention is incorporated, the rod I05 is presseddownwardly to move the switching element 23 to its full-line positionshown in Fig. 1, and a plurality of records are placed in thephonograph. Thereafter, the knob 41 is rotated in a counterclockwisedirection until the control member 48 opposite No. 1 on the plate 46 isopposite the pointer 50 in Fig. 2. As has been previously described,each one of the control members 48 controls the playing of acorresponding record in the automatic phonograph. After the controlmembers 48 are set relative to the pointer 50, the operator presses intothe the control members opposite Nos. 2 and 5 are in thesecond-position.

With the play-control mechanism in the assumed position, the controlmember 48 opposite No. 1 (Fig. 2) will be above the contact 5| but outof engagement with it, and the leg will be in the path of the lever 3|(Fig. 7).

After th first record is played on one side, the tripping mechanismpreviously referred to initiates the rotation of the cam wheel I3through a cycle of operation. The first operation which is performed bythe cam wheel I3 is to close the contacts 59 and 60. This is broughtabout by the cam portion I4 moving the contact 59 into engagement withthe contact 80. However, since the contacts 43 and 5| are open, theelectromagnet 56 is not actuated. This leaves the leg 65 in the path ofthe lever 3| and the lever 66 remains out of the path of the pin 24 onthe switching element 23.

As is clear from the description, the switching element 23 will be inthe full-line position (Fig. 1) during this cycle of operation of thecam wheel I3. With the switching element 23 in this position, the member30 is guided over the path formed by the grooves I8, I9, 2| and 20 sothat the member 36 cooperates with record-reversing mechanism to turnover record No. 1 on the tumtable. One form of mechanism foraccomplishing this function is described in United States Patent No.2,012,185. When the pin 29 of the member 30 engages the heel 21 duringits movement in the cam groove 2|, it moves the switching element 23from the full-line position to the dotted-line position shown in Fig. 1.

While the cam portion I4 is in engagement with the contact 59, theforward cam element I5 (see Fig. 1) moves into engagement with the pin33 and begins to pivot the lever 3| in a clockwise direction (Fig. 3).The continued movement of the cam wheel I3 brings the adjustable cammember I6 into engagement with the pin 33 and the lever 3| is movedfurther in a clockwise direction (Fig. 3). When the lever 3| has movedhalf the distance between the dotted-line position and the full-lineposition shown in Fig. 3, it is stopped by the leg 65. The stopping ofthe lever 3| by the leg 65 forces the member I8 to move in a clockwisedirection (Fig. 3) against the biasing action of the spring I 1.

During the clockwise movement (Fig. 3) of the lever 3|, Just referredto, the member 34 engages the gear 43 and moves it, the shaft 4| and theplate 46 in a counterclockwise direction (Fig. 3) a distance midwaybetween the control members 48 at No. 1 and No. 2 in Fig. 2.

As the cam wheel |3.continues to rotate, the member I6 and the secondcam element I5 are moved out of the path of the pin 33 and permit thespring 38 to move the lever 3| in a counterclockwise direction (Fig. 3)to its normal dottedline position (Fig. 3). As is clear from thedescription, the ratchet mechanism shown in Fig. 6 prevents thecounterclockwise movement of the lever 3| from transmitting motion tothe gear 43. Thereafter, the cam wheel |3 finishes its cycle of rotationand the phonograph is ready to reproduce the opposite side of record No.1.

After the opposite side of record No. 1 is reproduced, the trippingmechanism again initiates the rotation of the cam wheel I3. Since,during this cycle of operation of the cam wheel |3, the contacts 5| and52 will again remain out of engagement with each other, the play-controlmechanism will function in the same manner as it did during the previouscycle. During this cycle, the plate 46 is moved to position the controlmember 48 opposite No. 2 (Fig. 2) opposite the pointer 50 after the camportion H has moved into and out of engagement with the contact 56. Withthe control member 48 opposite No. 2 in this position, it will be inengagement with the contact 5| and hold it in engagement with thecontact 52 until the gear 43 is again moved by the lever 3|. Also,during this cycle of operation, it will be evident that the pin 28 ofthe member 30 is guided by the grooves l8, I9, 22 and or the second campath to move the member to cooperate with the record-moving mechanismfor changing a record on the turntable. One embodiment of such mechanismis described in United States Patent No. 2,012,185. As the pin 29 movesin the cam groove 22, it engages the heel 28 to move the switchingelement 23 from its dotted-line to its full -line position shown in Fig.l.

After one side of record No. 2 is reproduced, the tripping mechanismagain initiates a cycle of operation of the cam wheel l3. During thiscycle, when the cam portion |4 moves the contact 59 into engagement withthe contact 60, the electric circuit to the electromagnet 56 is closedand the electromagnet 56 is actuated to move the leg 65 out of the pathof the lever 3| and to move.

the lever 66 for positioning the switching element 23 into thedotted-line position shown in Fig. 2. As the cam wheel i3 continues torotate, the pin 24 moves into engagement with the lever 66, whereby theswitching element 23 is moved from the full-line position to thedotted-line position shown in Fig. 1. With the switching element 23 inthis position, the member 30 again'is permitted to follow the secondpath formed by the cam grooves 8, I9, 22 and 20. This again permits themember 30 to cooperate with record-moving mechanism for changing arecord on the turntable. As the pin 29 of the member 30 moves in the camgroove 22, it engages the heel 28 of the switching element 23 and movesit from the dotted-line position to the full-line position shown in Fig.1.

While the cam portion I4 is in engagement with the contact 59, theforward cam portion I5 (Fig. 1) moves into engagement with the pin 33,and the lever 3| is moved in a clockwise direction (Fig. 3). Continuedrotation of the ca'mwheel it brings the member l6 into engagement withthe pin 33. And, since, during this cycle of operation, the leg 65 isnot in the path of the lever 3|, the lever 3| is moved in a clockwisedirection to the full-line position shown in Fig. 3. During theclockwise movement (Fig. 3) of the lever 3| just described, the gear 48,the shaft 4| and the plate 4t: are moved, in a counterclockwisedirection (Fig. 1), the distance between the control members 48 oppositeNos. 2 and 3 in Fig. 2. This brings the control member 48 at No. 3 (Fig.2) over the contact 5| but not into engagement with it. Thereafter,during further rotation of the cam wheel l3, the adjustable member l6and the second cam element l5, due to their shape, permit the spring 38to move the lever 3| in a counterclockwise direction (Fig. 3) to itsnormal dotted-line position shown in Fig. 3. After the cam wheelfinishes its cycle of rotation, the phonograph is ready to reproducerecord No. 3..

While there has been described what is at present considered thepreferred embodiment of the invention, it will be obvious to thoseskilled in the art that various changes and modifications may be madetherein without departing from the invention, and it is, therefore,aimed in the appended claims to cover all such changes and modificationsas fall within the true spirit and scope of the invention.
